Always read the Material Safety Data Sheet (MSDS) before using and refer to each product’s specific technical resource material for precautionary items in handling each product. The following information was written as a reference on the precautionary items for general handling of fluoroelastomers.
1 Compounding agent and facility
The common fillers and facilities for commodity rubber can be used for DAI-EL. The mixing mill needs to be cooled. Finely divided metallic powder or filler, such as aluminum and magnesium, or amine compounds of more than 10% should not be used as compounding agents for DAI-EL because such materials are known to decompose vigorously at moderately elevated temperature.
2 Storage and remixing
Store the compound in a tightly closed package in a cool and dry place.
Another milling before use is recommended when the compound is left for more than three days. Too tight a nip between the rolls in the mixing mill may cause scorching. Be sure to cool the rolls well whenever the compound is milled with tight nip.
3 Molding/Curing
The work area should be adequately ventilated at all times because a small amount of toxic gases(e.g. HF, acetone, methanol, acetaldehyde, methyl iodide and carbon monoxide) may be evolved during curing.
4 Material handling
A slight amount of hydrogen fluoride vapor may be produced during use at high temperatures (above 200℃). The room should be well ventilated.
Do not smoke in the work areas as harmful vapors may be inhaled when cigarettes are exposed to the powder of DAI-EL. After handling the powder of DAI-EL, knock off any dust from your hair or clothing and wash your face and hands thoroughly before smoking.
5 Disposal
Do not incinerate DAI-EL as this can produce harmful vapors. Disposal should be done in accordance with local laws and regulations.
